Depart from Saturn and explore the distant starry skies of the solar system. This is easier said than done. But it is very difficult to implement it. Not to mention anything else, it's just that in the starry sky, the long journey is not something that ordinary flying machines can conquer.

Even the Thunder takes a lot of time to explore the entire solar system over long distances.

It is calculated according to the position and distance of the eight planets in the solar system. The distance between the Earth and Saturn is about 1.3 billion kilometers, and the distance between the Earth and Uranus can reach 2.7 billion kilometers!

If we say that the distance from the Jupiter system to Saturn is equivalent to the entire distance of the Thunder from Earth to Jupiter. Then, the distance from Saturn to Uranus is equivalent to the entire distance of Thunder from Earth to Saturn.

From Saturn to Uranus, there is at least about 1.4 billion kilometers in between. Even if the Thunder were to go full speed, it would take two months to reach Uranus. Moreover, the Thunder's driving in the cosmic starry sky has many considerations.

For example, you need to dodge some sudden asteroids and the like. So, it's impossible to go full throttle. Yun Lei and others, after leaving Saturn, took about three months to reach Uranus.

Uranus is a very special existence among the eight planets of the solar system. The other planets are all sitting upright and revolving around the solar system, but this Uranus is lying in orbit and revolving around the solar system. The material composition of Uranus is similar to that of Jupiter and Saturn. Therefore, it is classified as a gas superstar.

The main components of Uranus' atmosphere are hydrogen and helium. In addition to this, there are large amounts of water, ammonia, methane, and other substances that exist in solid form. Because it is so far away from the sun, Uranus has the lowest temperature of any planet in the solar system. It can reach minus 224 degrees Celsius.

Because it is so distant and cold, Uranus's atmosphere is made up of solid ice formed by the condensation of various materials. This is the geologic letter of Uranus. Underneath this is a hot, dense fluid of water, ammonia, and other volatile substances.

Uranus's silicate rocks have a small core and no magma, and these fluids rich in various organisms at high temperatures and pressures are highly conductive, so they replace the magma on Earth and under the earth's crust. A huge magnetic field was built for Uranus.

And this ocean of liquid fluids is huge. But with the oceans on Earth, it's very different. It can neither boil nor evaporate, and even the main ingredient is not water. Because it is mixed with various substances and is under high temperature and high pressure. Therefore, among these fluids, although there is not necessarily no primitive life.

However, it is too difficult to break the weight of Uranus, which is more than 13 times more massive than Earth, to explore this area. With the Thunder's current material reserves, or even technical reserves, it can't do this.

Even for the Atlanteans, exploring alien planets and developing various power and energy systems is a very easy and easy task. However, when it comes to drilling a planet, it is also difficult.

Therefore, these scientists on the Thunder do not have much enthusiasm for exploring Uranus. After reaching Uranus, leaving only a few moons, it flew past Uranus and towards Neptune's position.

The distance between Neptune and Uranus, in astronomical units, is not too exaggerated. It's just about ten astronomical units short, but one astronomical unit is almost 150 million kilometers.

Usually, many people call it an astronomical amount when they evaluate a person's net worth or a certain transaction amount reaching tens of millions, but in fact, a huge number for ordinary people still seems small in front of the real astronomical unit!

Converting the astronomical units, the distance between Uranus and Neptune is also about 1.5 billion kilometers.

This value is almost 100 million kilometers farther than the distance from Saturn to the Sun.

Unlike Uranus, Neptune is farther away from the Sun, and its cloud top temperature can reach minus 218 degrees Celsius. However, Neptune's inner core is much larger than that of Uranus. The size of its planetary core is almost the size of an Earth.

So, although Neptune is smaller than Uranus in diameter and volume, it has a greater mass than Uranus. And it has the strongest storm in the solar system, with winds of up to 2,100 kilometers per hour!

The temperature of its core can reach almost 7,000 degrees Celsius.

Moreover, Neptune's planetary structure is similar to that of Uranus. Because the temperature inside the earth's core is relatively high. So, although Neptune is smaller than Uranus, its planet's subterranean ocean, made of water and ammonia, or subsurface fluid oceans, may be larger than Uranus.

Of course, there may also be some primitive life among them. It's just that Neptune's hard and frozen surface is also very difficult to break. Therefore, there is no need to explore carefully. Now, the Thunder can only pass by.

The only thing that can make Thunder linger a little longer next to Neptune is Neptune's huge moon, Triton. The diameter of Triton is about 2,700 kilometers. Among the bunch of moons in the solar system, it is considered to be the largest one. Moreover, there are ice volcanoes on it.

According to the detection of the Thunder, the ice volcano on Triton can erupt a huge liquid fountain up to eight kilometers high. Just like Europa. However, after the Thunder probe, it was found that these huge liquid fountains were only a mixture of liquid nitrogen, methane and other substances.

The surface is so cold that not only will the water freeze into icebergs, but also carbon dioxide, carbon monoxide, and methane will freeze into icebergs on its surface! The only thing these icebergs can do is to make Triton itself more reflective of light and look brighter.

Other than that, there is no use.

Because Uranus and Neptune themselves are cold and huge, these two huge planets have the name of ice giants in astronomy. The Thunder didn't linger long as it flew over the two ice giants, and continued to fly towards deep space.
